After so many time without making any input here , I am going to amend it a little bit

I have done a little graphical description of the form of the main riders across the season. It is done using a method named "moving median" that try to get the typical position that a rider would get in (almost) each GP, eliminating "anomalous" races.

An important part of the total official points table is due to DNFs or others more or less casual events (weird wet race results, for example). Median average takes out "random" results and tends to focus in patterns. So, these graphics give a slightly different view of the season.
